Fig. 1 is a view showing a frame structure of a dedicated vehicle (PBV) to which the present disclosure is applied, and there is an example in which a frame 1 may be divided into a front portion FP, a middle portion MP, and a rear portion RP in a length direction of the vehicle, and a battery 3 is mounted on an inner side of the middle portion MP.
Fig. 2 to 6 further illustrate a frame structure for a PBV according to an embodiment of the present disclosure, the frame structure including: an inner panel 7 connected to the rear of the middle portion MP of the side member 5 to form the inside of the rear portion RP of the side member 5; a front outer panel 9 connected to the rear of the middle portion MP of the side member 5 and joined to the outside of the inner panel 7 to form a closed cross section; a center outer plate 13 connected to the rear of the front outer plate 9 and joined to the outer side of the inner plate 7 to form a space into which the rear suspension member 11 is joined; and a rear outer panel 15 connected to the rear of the central outer panel 13 and joined to the outer side of the inner panel 7 to form a closed cross section.
In other words, the rear portion RP of the side member 5 is made of the inner panel 7 on the vehicle inside, and the front outer panel 9, the center outer panel 13, and the rear outer panel 15, which are sequentially arranged in order from front to rear on the vehicle outside. The center outer panel 13 is configured to form a space inside the side member 5, to which the rear suspension member 11 is joined.
Thus, the front side of the rear wheel suspension is allowed to be tightly and firmly fixed to the frame 1 without protruding to the outside of the vehicle, and a sufficient distance is ensured between the side members 5 on both sides, thereby ensuring easier installation of the battery 3 in the PBV.
The inner panel 7 forms an upwardly curved portion KU extending upwardly from the rear portion of the intermediate portion, and the center outer panel 13 is mounted in the rear portion of the intermediate portion MP at a position where the upwardly curved portion KU starts.
The center outer panel 13 includes: a front bulkhead 17 sealing the rear of the front outer panel 9; a rear bulkhead 19 sealing the front of the rear outer panel 15; an upper cover portion 21 joined to the upper surface of the front outer panel 9 and the upper surface of the rear outer panel 15 between the front bulkhead 17 and the rear bulkhead 19; and an outer cover portion 23 to which the front partition 17, the rear partition 19 and the upper cover portion 21 are connected and which forms the outer surface of the side member 5.
In other words, as shown in fig. 5 and 6, one plate member is bent a plurality of times so that the front bulkhead 17, the rear bulkhead 19, and the upper lid portion 21 are integrally formed around the outer lid portion 23.
Since the center outer panel 13 as described above is joined to the outside of the inner panel 7 at a position where the upwardly curved (key-up) portion KU of the side member 5 starts, the opening portion OP into which the rear suspension member 11 can be inserted is formed on the lower side of the upwardly curved portion KU of the side member 5 through the front bulkhead 17, the rear bulkhead 19, and the outer cover portion 23 of the center outer panel 13 and through the inner panel 7.
In other words, the center outer panel 13 forming the opening portion OP is installed in the upwardly curved portion KU of the side member 5, and the inner panel 7 is installed on the inner side of the center outer panel 13 to form the opening portion OP.
Accordingly, the rear suspension member 11 is engaged through the opening portion OP provided on the lower side of the upwardly curved portion KU of the side member 5 in the inserted state, so that the rear suspension member 11 is engaged to the inside of the side member 5 without protruding to the outside, thereby allowing tight vehicle assembly.
Further, as described above, the front bulkhead 17 of the center outer panel 13 prevents foreign matter from entering the closed cross section formed by the front outer panel 9 and the inner panel 7, and enhances the rigidity of the joint portion of the center outer panel 13 to the front outer panel 9 and the inner panel 7, so that it is possible to provide stronger rigidity against rear-end collisions and the like for vehicles.
The rear bulkhead 19 of the center outer panel 13 also prevents foreign matter from entering the closed cross section formed by the rear outer panel 15 and the inner panel 7, and enhances the rigidity of the relevant portion.
The support portions 25 rotatably supporting the rear suspension member 11 are formed so as to protrude toward each other in the outer cover portion 23 of the center outer plate 13 and the inner plate 7 opposite thereto, respectively.
In the present embodiment, the support portions 25 protrude in a circular shape and are provided with shaft mounting holes 27, respectively, into which the rotation shafts of the rear suspension members 11 can be inserted.
Accordingly, a structure is formed such that the rear suspension member 11 can be smoothly rotated according to a change in the relative position of the wheel with respect to the frame while the vehicle is running without being disturbed by other portions of the side members 5, so that the suspension can be normally operated without generating noise or vibration.
In the present embodiment, the first joining surface 29 to be joined to the inner panel 7 and the second joining surface 31 to be joined to the front outer panel 9 are integrally formed in the front bulkhead 17 of the center outer panel 13, and the third joining surface 33 to be joined to the inner panel 7 and the fourth joining surface 35 to be joined to the rear outer panel 15 are integrally formed in the rear bulkhead 19 of the center outer panel 13.
Further, a fifth joining surface 37 to be joined to the front outer panel 9 and a sixth joining surface 39 to be joined to the rear outer panel 15 are integrally formed in the upper cover portion 21 of the center outer panel 13.
The plurality of joint surfaces provided in the center outer panel 13 as described above are joined to the inner panel 7, the front outer panel 9, and the rear outer panel 15 by welding or the like, so that it is possible to ensure very high rigidity around the center outer panel 13, whereby it is possible to effectively prevent the battery 3 fixed in front of the center outer panel 13 from being damaged by an impact force transmitted from the rear of the vehicle.
On the other hand, the rear cross member 41, which connects the side members 5 on both sides to each other, is provided on the inner side of the portion forming the opening portion OP of the side member 5.
The rear cross member 41, which is joined to the inner panel 7 opposite to the portion where the center outer panel 13 is joined, extends in the lateral direction of the vehicle.
The rear cross member 41 is supported while being maintained at a distance from the rear of the battery 3 so that the impact force transmitted from the rear of the vehicle has minimal influence on the battery 3.
While particular embodiments of the present disclosure have been illustrated and described, it would be obvious to those skilled in the art that various other changes and modifications can be made without departing from the technical spirit of the disclosure.
